It generally refers to setting the text that will appear when the shell prompt is asking the user to type in a command, meaning, the shell needs work to do. The standard prompt in most shell environments is a single character, such as '#', '$', or '%'. By setting the prompt you can customize what appears when the system is idle and wants you to type in a command to do something.
The prompt is an indication that the system is waiting for work to do, i.e. waiting for you type in a command.
Depends on what you mean by a "job". You can compile a program.
The usual indication of running as the administrator in Unix is show a prompt that contains the '#' character as either the prompt or part of the prompt.
Most people set up their shell to give them an indication in the command prompt. But this isn't "built in" (the mechanism for doing so is built in to most shells, but you can use the same mechanism to change the prompt to pretty much anything you want).The command pwd on a Unix system should tell you "where you are".
Unix is a text file, not a web browser. :)
Widely used text-based operating system? Well, almost any Unix or Unix-like can be used in this way. X11 GUIs are an entirely optional application. Many Linux users only use the command line.

Use the shell variable PS1 to set the command prompt to whatever you need.

You can log in via telnet or ssh protocol for a command line prompt environment to Unix, or you can use a graphical user interface such as KDE or Gnome, or the CDE environment via X-windows. In any of these protocols, you must supply a username and password to successfully log into the Unix system.
You really can't. There is nothing in a prompt that would give that information.
